Getting error "dynamic function invoked with incorrect number of arguments" on code that works with Saxon and BaseX

[martin-honnen]

I have tried the following sample code

let $f := function($nums as xs:integer*, $f1 as function(*)) as xs:integer
                      {
                        if (empty($nums))
                          then 0
                          else head($nums) + $f1(tail($nums), $f1)
                       },
                 $F := $f(?, $f)
             return
                 $F(1 to 200)

on http://try.zorba.io/queries/xquery and get the compilation error

[XPTY0004] dynamic function invoked with incorrect number of arguments

Line 5, column 46.

When I try the same code with Saxon 9.5 or BaseX 7.9 it compiles and runs fine.

Fixed in PR #106 . William, can you review (but not merge)?
Thanks
